Creating Creamy White Chicken Enchiladas is simple if you follow these steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C).
2. Prepare Filling: In a large bowl, combine shredded chicken, sour cream, cream of chicken soup, diced green chilies, garlic powder, onion powder, cumin, salt, and black pepper. Mix until well combined.
3. Warm Tortillas: Heat the flour tortillas in the microwave for about 30 seconds to make them pliable.
4. Fill Tortillas: Spoon about ¼ cup of the chicken mixture onto each tortilla. Roll them up tightly and place them seam-side down in a greased baking dish.
5. Make Sauce: In a separate bowl, mix the chicken broth with any remaining chicken filling. Pour this mixture over the rolled tortillas in the baking dish.
6. Add Cheese: Sprinkle the additional shredded cheese evenly over the top.
7. Bake: Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the cheese is bubbly and golden.
8. Garnish: Remove from the oven and let cool slightly. Garnish with fresh cilantro if desired.
